Sailing Deep by Noah Harris

Dylan frowned, “Who are you?” He demanded in a whisper.
“I’ll tell you later. For now, kiss me.”
He hadn’t thought that Blake could get any closer. He was wrong. Blake’s body seemed to melt against his, relaxing so that every curve, every line, every inch, was pressed together. He could feel it through the layers of clothing. When Blake kissed him this time, it was strangely slow. He captured Dylan’s lips and held them with a firm tenderness that made Dylan’s head spin. It had been so long since he had kissed anyone. It had been so long since he had been this close to anyone. He had forgotten what it felt like.
Dylan’s mission: assist his Navy SEAL team as they infiltrate enemy territory and gather Intel on the new shifter pack called the Shadow Pack through distant observation.
Blake’s mission: infiltrate and live within the Shadow Pack and gather any useful information and data from the inside as one of them.
One is a SEAL, and the other is a spy. Their missions were never supposed to cross, yet one fateful accident during a full moon intertwines their fates. Dylan finds himself in the middle of the Shadow Pack and under the charade that he’s Blake’s mate. They must learn to live and work together, or risk exposing both of their covers, and Dylan’s team. Blake is charming, flirty, cocky, and irritating; yet Dylan finds himself strangely drawn to the man. Blake’s strength of will and patience are put to the test, but Blake is patient, and he’s not willing to give up so easily.
